Microfat and nanofat both begin with the patient’s own harvested fat, but processing changes how each material can be used. They are not interchangeable and neither is automatically appropriate for every face. Microfat is used to restore selected volume; nanofat is a finely processed suspension used for selected superficial skin-quality concerns.
Microfat versus nanofat
| Feature | Microfat | Nanofat |
|---|---|---|
| Main objective | Structural volume replacement | Selected superficial skin-quality treatment |
| Fat cells | Intact adipocytes are preserved | Most mature adipocytes are disrupted during processing |
| Typical placement | Small deposits in deeper or intermediate planes | Superficial placement in carefully selected areas |
| Does it lift tissue? | No mechanical lifting; may support contours | No |
| Predictability | Some volume integrates; some may be reabsorbed | Skin response and evidence vary |
When microfat may be considered
Microfat can be placed in small amounts to address volume loss in areas such as the temples, cheeks, lid-cheek junction or selected perioral regions. Placement depth, parcel size and vascularity influence integration. Overcorrection can create heaviness or irregularity, and weight change may alter retained fat over time.
Microfat does not reposition descended tissues. When jowls, brow descent or neck laxity are the principal concern, surgery directed at those structures may be more appropriate. Learn why facial fat-graft retention varies.
What nanofat can—and cannot—do
Nanofat is created through emulsification and filtration. Because its volume-producing adipocytes are disrupted, it should not be described as a filler. It may be considered for selected superficial texture, fine-line or dyschromia concerns, but clinical evidence is still evolving. It should not be promised to regenerate skin, erase pigmentation or replace dermatologic treatment.
Under-eye darkness can result from shadow, pigment, visible vessels, edema or a combination. Nanofat will not correct every cause. A careful eyelid and midface assessment is needed before choosing treatment. See what blepharoplasty can and cannot treat under the eyes.
Can both be used in one operation?
Yes, when there are separate indications. Microfat may be used for a structural hollow while nanofat is considered for an overlying superficial concern. The decision is based on anatomy rather than a package. In Dr. June Favarin’s Hybrid Blepharoplasty planning, eyelid support, brow position, fat preservation or repositioning, microfat, nanofat and skin treatment are evaluated separately; not every patient receives every component.
Previous injectables and ultrasound
Prior fillers, biostimulators, threads and permanent materials can contribute to swelling, fibrosis or distorted volume. Patients should provide names, dates, quantities and treatment locations whenever possible. Dermatologic ultrasound may help identify material and guide planning. Hyaluronidase acts on hyaluronic-acid filler only and may not fully correct chronic tissue changes.
Risks and recovery
Expected effects include swelling, bruising, tenderness and temporary asymmetry at the face and donor site. Possible complications include infection, contour irregularity, prolonged edema, cysts, fat necrosis, pigmentation changes, undercorrection or overcorrection. Rare vascular complications are serious, which is why knowledge of facial anatomy and conservative technique matter. Results should be assessed after swelling settles, and a refinement may occasionally be considered.
Planning for international patients
Fat grafting is often combined with another facial procedure, so recovery and travel timing depend on the complete operation. Belvivere performs surgical cases in a hospital and coordinates early follow-up in Criciúma. International patients can review preparation for surgery abroad and the concierge support. An in-person examination remains necessary before the final plan.
